SHER BROOK f MW@ AT TO RN EY United States YPatent O 3,124,886 WRAP-AROUND GOODYEAR WELT SEAM CONSTRUCTION Victor A. Sherbrook, 164 Colonel Huntl Drive, Abington, Mass. Filed Dec. 7, 1961, Ser. No. 157,652 2 Claims. (Cl. 36-17) This invention relates to a new `and improved wraparound seam for Goodyear welt constructions for cemented or moulded sole attaching processes, and the principal objects of the invention reside in the provision of a waterproof welt seam which of course is very desirable in many different kinds of shoes; the provision of `a more iiexible welt shoe; the provision of a wrap-around seam of the class described Ewhich is less expensive to manufacture, eliminating many shoe making operations otherwise necessary on Goodyear welts such as edge-making and sole-finishing; the provision of a shoe of the construction described which is much lighter than made by current welting processes; yand the provision of a wraparound seam for Goodyear welt shoes to which any kind of sole desired may be cemented, the new wrap-around seam providing a base for attachment of the outer sole thereto.

Further objects of the Vinvention reside in the provision of a new wrap-around seam as described which may embody a decorative bead, braid, concave groove, tape reenforcement, etc., the wrap-around seam preferably being made from elongated strips of rubber-like material cut to desired widths and thicknesses, or of suitable plastic material which can be extruded in continuous lengths.

The invention is carried out in general by using a wrap edge welt construction which however instead of being brought down into contact with the edges of the outer sole, is instead wrapped completely over the seam and cemented to the sewing rib and the insole prior to attachment of the outer sole.

The invention further relates to arrangements and combinations of parts which -will be hereinafter described and more particularly set forth in the appended claims.

Reference is to be had to the accompanying drawings, in which FIG. 1 is a sectional view illustrating the invention partly formed;

FIG. 2 is a view similar to |FIG. l showing the new construction completed but without the outer sole;

FIG. 3 is an enlarged View illustrating the welt;

FIG. 4 is a view similar to FIG. 3 showing a modified form of welting;

FIG. 5 is a section on line 5-5 of FIG. 4;

FIG. 6 is a view similar to FIG. 2 illustrating the modied welting in use;

FIG. 7 is a View in elevation illustrating the appearance of a shoe with the modified welting of FIG. 4 utilized, and

FIGS. 8 and 9 are views similar to FIGS. l and 2 respectively but showing a modification.

In carrying out the present invention, it is pointed out that the reference numeral 10 indicates an insole of any construction having applied thereto a sewing yrib i2. This sewing rib may be of any constnuction but it is preferred that it be formed of tape as shown and described in my Patent-s No. 2,713,692 and No. 2,985,555 among others. Other forms of sewing ribs or lips may also be used if desired.

The upper leather is indicated at 14 and is attached in the usual way .and the welting that is the `form of the present invention is indicated `by the numeral 16 generally and this is connected by the stitching at 1S together with the upper leather.

The welting 16 is elongated and may be provided in l-CC substantially continuous strips. It is of considerable width and it is shown in FIG. 1 in dotted lines in more or less the position that it normally assumes when attached to the sewing rib. Ordinarily this welting is aligned with and cemented to the edge of the outer sole (not shown) more or less in the solid line position of FIG. l, but in the present case it is turned completely over in the direction of the arrow in FIG. l to closely engage and be tightly cemented to the rib and also the insole as shown in FIG. 2.

The welting 16 is preferably provided with an elongated fabric or similar reenforcernent stripping as at 20 and this is provided in an elongated gutter shown at 22 so that the `folding over operation is made easier and in fact is even initiated in the Iwelt stripping itself before it is applied. It is to be understood that the welting is done in more or less conventional manner `as is valso the inseam trimming, etc., the novel step being illustrated in FIG. 2 vwhere the welting is wrapped completely around over the seam and is pressed to the insole and made as at as possible. Then the outsole is cemented to the welt and the insole and no stitching is necessary for this operation, see outsole 21 in FIG. 2.

It will be seen that there is a bottom filler cavity provided but this is a good deal less than the conventional cavity and lalthough the drawings are necessarily exaggerated in FIGS. l and 2 in order to illustrate the invention, the bottom iiller cavity is almost eliminated and no iiller is actually needed. If no ller is used, the outer sole is in just about flat condition when cemented to the welting described which provides an `outer edge support particularly desirable in some kinds of shoes such as for instance golf shoes. Filler material can be used if desired, in which case the sole will be slightly convex as is usual.

Also no roughing of the welt is needed as the welt material used is conducive to attaching by cement and in this regard it is emphasized that a rubber type of material is preferable although plastics and other iiexible material can be utilized. Furthermore, the entire sole may be treated in the manner stated so that heel seating is avoided and the outer sole being in one piece can be applied at one time including the heel, but heel seating and a separate heel may be used if desired. The foot is cradled to some extent ,because of the outer edge support referred to when no filler is used, and the shoe is therefore clearly more flexible aswell las being lighter in weight.

-If desired, a moditied form of welting can be utilized as shown in FIGS. 4 to 7 inclusive. In this case the Welting is indicated at 24, the reenforcement material at 26 and at the side of the lwelting opposite the reenforcement there is applied the folded-over tape as for instance as indicated at 28 having a decorative bead 30 which may comprise la strip of material encased in the fold 32, or the fold 32 itself may form the decoration. This fold can be apertured as at 34 in FIG. 5 so as to show the strip 30 through the `fold 32. Other forms of decoration may also -be utilized such as braid, concave grooves, and other kinds of oma-mental and contrasting tapes.

When this welting is utilized, it will appear as shown in FIGS. 6 and 7, but otherwise the construction is the same as before. In FIG. 6 the inner sole is indicated at 36, the sewing rib at 38, the folded-over welting is indicated at 24, the upper being shown at 453, and the relative position of the outsole is indicated at 42. Although the welting 24 is illustrated in FIG. 7, it usually is practically invisible because made of material very similar to the appearance of the outsole itself.

Referring now to FIGS. 8 and 9, the insole is indicated at 50, the sewing rib at 52 and the upper leather at 54. The welting strip is shown at 56 and the parts including the stitching 58 are as thus far described the same as in FIG. 1. However in this case, just after cementing the seam, welt and insole, a cord 60 is is laid around the seam (see FIG. 8) and after the cement has dried suliciently, the welt strip is wrapped around over the rib and insole as in FIG. 2 but now the appearance is as in FIG. 9.

This provides the welt with an extended rounded look around the seam line and in addition there is a atter and larger surface on the insole side to which the outsole will adhere. By varying the diameter (and section) of the cord 60, slightly different contours and edge eX- tensions are achieved and of course the fabric cord (or extruded plastic) which may be used at 60 may be made in continuous rolls with a pressure sensitive coating of cement which would facilitate the application thereto.

It will be seen that the new wrap-around seam for Goodyear welt construction provides a seam that is waterproof and makes a more exible welt shoe that is less expensive to manufacture and at the same time is lighter.

Furthermore, the new welting lends itself to the provision of decorative strips, etc. as described and in cases where the filler material is' omitted the foot is cradled and receives outer edge support because of the seam construction.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein shown otherwise than as set forth in the claims, but what I claim is:

1. A Goodyear welt construction for shoes comprising an insole, a sewing rib on the insole adjacent the edgcs thereof, an upper secured to the rib, and a welt strip secured to the rib at the outer aspect thereof, with a portion of the upper between the welt strip and the rib, the welt strip being folded over the rib and cemented down onto the same and to the insole at the inner aspect of the rib, said welt strip covering the rib, and the rib being folded down onto the insole so that the rib and folded-over welt strip form a relatively small projection in the area of the rib on the insole, and an outsole secured onto the folded-over welt strip and the insole.

2. The Goodyear welt construction as recited in claim 1 including a longitudinal gutter adjacent an edge of the welt strip and a longitudinal reenforcing strip in the gutter.
